Abstract

Radon gas is one of the main causes of lung cancer, the release of this gas in water resources can lead to major environmental hazards. The purpose of this study was to measure the concentration of radon gas in groundwater of the Jiroft plain and determine its relationship with active faults in the region. In this regard, 40 samples of wells water were collected from Jiroft plain and the RAD7 was used to calculate the concentration of dissolved radon gas in them. According to the results, 67% of wells have more than the limit of radon concentration in the studied area. The zoning map of the radon gas concentration was prepared By performing an interpolation operation. The study area was classified into four classes: very high, high, medium and low in terms of radon gas concentration. So that the area is about 54,000 hectares are in a high and very high concentration range. While the Jiroft city is in the high concentration of radon gas. In order to determine the relationship between the high concentrations of radon gas and faults in the region, the weights of evidence method were used. The results of this method indicate that there is a high correlation between high and very high concentrations of radon gas and main faults. The greatest association was found in 1000 meters of faults and this association will be reduced by Getting away from the faults.
